0023115: Polygon offset doesn't applied in Viewer3D sample

Graphic3d_AspectFillArea3d: use Aspect_POM_Fill polygon offset mode by default

Graphic3d_Group: disable texture mapping if invalid texture ID is specified

AIS_InteractiveObject: remove Fill() method, polygon offset parameters
should be applied explicitly in Compute() method or by SetPolygonOffsets()

AIS_TexturedShape: Compute() now takes polygon offsets into account
